/clone moving doors only moves half of them

Using clone with the move parameter at the end on a door yields in the bottom half of the door to be moved, and the top half to jump to the west side of the block it is in.

Reproducing:

• Place a door down (material doesn't matter)
• Place a command block down from 2 blocks from it.
• Type the clone command in the command block, so that the door gets moved away from it's original position (does not matter how far)
• Execute the command block

EDIT: Same applies for pistons (without the upper part snapping to a side of course), tall grass, and probably moat/all double-block as well. I also associate it with a crash, for which I have created a report: https://bugs.mojang.com/browse/MC-61183
